LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 251,973, dated January 3, 1882. Application filed May 31, user. (No model.)

To all whom it may concern:

Be it known that I, CHARLES N. TUCKER,

' of Great Falls, of the county of Strafi'ord and scribed in the following specification and represented in the accompanying drawings, of which-- j Figure l is a top view, Fig. 2 a longitudinal section, and Fig. 3 a transverse section, of a shuttle provided with my invention, the nature of which is defined by the claims hereinafter presented. Fig. 4 is a horizontal and longitudinal section of the spindle and its expander.

The improvement relates to mechanism for expanding the shuttle-spindle in order to enable it to firmly hold the cop while the spindle may be in use.

In the drawings, A denotes the body of the shuttle; B, the spindle, and C the operativespring of the lattrr, arranged and applied in the ordinary way, the spindle being an expansive one-that is to say, it is split lengthwise from near its toe or point to or through its heel, and has within it an expander, D, which is tapering or wedge-shaped, as shown. This expander, on being drawn back within the spindle, expands it laterally, the spindle on the expander being forced forward within it, contracting by its inherent elasticity. This expander, at its rear part, is bent at a right angle and extends upward through a slot, a, in the spindle, and is jointed to the wrist of a link or doubleorank, E, such crank being arranged in the body of the shuttle and pivoted thereto or to a metallic carrier, F, inserted in the said body and formed as represented. The link or double crank straddles the front portion, 1), of the spring 0 in manner as shown in the drawings, so as to-leave the spring free to bear and act on the heel or head 0 of the spindle, the shuttle-body being suitably recessed to admit of the necessary vertical play of the link or double crank within it. On raising the spindle in the shuttle-body the eX-' pander will be forced forward within the spindle, which in the meantime will contract laterally; but on the spindle being prcvided with 0 a cop and moved down into the chamber of the shuttle-body the-expander, during the downward movement of the spindle and cop, will be drawn backward within the spindle and will expand the latter so as to cause it to hold the placed on it while the spindle may be in the act of being turned down into the shuttle-body, and therefore I make no claim to such in the abstract, nor do I claim the expander hooked at its rear part and over a stationary pin and kept thereon by a spring, all as shown in the British Patent No. 1,099 for 1854.

What I claim as my improvement is as fol lows, iviz:

1. The link ordouble crank E, arranged and combined substantially as set forth,wi:h the shuttle-body, the expander, and the split or expansive spindle, all being essentially and to operate as specified.

2. The link or doublecrank and its pivotal carrier inserted in the shuttle-body, in combination therewith and with the expansive spindle and its expander, all being adapted substantially as set forth.

3. The link or double crank, in combination and arranged with the shuttle-body, the expansive spindle, and its expander and operative spring, substantially in manner as shown and described.

CHARLES N. TUCKER.
